Rounding Numbers

WALT - round numbers to the nearest whole number.

2,469.491
2,469.491 is between 2,469 & 2,470. Since I will be rounding it to the nearest whole number I take a look at the first whole number in the ones place then look to the right which is the tenths place and since 4 is lower than 5 I will be rounding down. Which brings you 2,469

    41,806.608
41,806.608 is between 41,806 & 41,807. Since i am rounding it to the nearest whole number i take a look at the first whole number in the ones place then look to the right which is the tenths place and since 6 is higher than 5 I will be rounding up to the nearest whole number. Which brings you 41,807.

    219,411.099
219,411.099 is between 219,411 & 219,412.Since i am rounding it to the nearest whole number I take a look at the first whole number in the ones place then look to the right which is the tenths place and since 0 is lower than 5 I would be rounding down to the nearest whole number. Which gives you 219,411
           

     658,414.584
658,414.584 is between 658,414 & 658,415. Since I will be rounding it to the nearest whole number I first look at the whole numbers in the ones place then look to the right which is the tenths place and since 5 is lower than 5 I will be rounding down. Which brings you 658,414

     3,605,435.85
3,605,435.85 is between 3,605,435 & 3,605,436. Since i am rounding to the     nearest whole number I take a look at the first whole number in the ones place then look to the right which is the tenths place and since 8 is higher than 5 I will be rounding up to the nearest whole number. Which would give you 3,605,436














     WALT - round numbers to the nearest Ten.

1. 2,469.491
2,469.491 is between 2,460 & 2,470. Since I will be rounding it to the nearest ten. I first take a look at the tens place then look to the right and change the 9 to 0. Now since 9 is higher than 5 I will be rounding up to 2,470

2. 41,806.608
41,806.608 is between 41,800 & 41,810. Since i am rounding it to the nearest ten i first take a look at the ten place and to decide if to round up or down and since 6 is higher than 5 I will be rounding up to 41,810


3. 219,411.099
219,411.099 is between 219,410 & 219,420.Since I am rounding it to the nearest tens I first take a look at the tens place then look to the right which is the ones place and since 0 is lower than 5 I will be rounding down to the nearest tens. Which is 219,410

4. 658,414.584
658,414.584 is between 658,410 & 658,420. Since I am rounding it to the nearest tens I first take a look at the tens place then look to the right which is the ones place and then change the 4 into 0. Now since 4 is lower than 5 I will round it to 658,410
5. 3,605,435.85

3,605,435.85 is between 3,605,430 & 3,605,440. Since I am rounding it to the nearest tens I take a look at the ten place then look to the right which is the ones place and then change 5 into 0. Now since 5 is to 5 you still have to round down to 3,605,430.

Today I've had learnt how to do Rounding Numbers. These equations were hard to explain but at the end I had a go at trying to explain these equations to the nearst tens. These equations are easy and hard to get through. When solving Rounding up or down numbers you have look in the tens place and replace the less number zero. So at the end you will find or get your answer.

Prototec

Today during this morning block I had done Prototec. This prototec was very easy for me to do because I understand the equations on prototec. I timed myself on stage 5. I got 98 percent and that is a great result. Nexts I have to move to stage 6 and I have to get past 85 percent to move on to stage 7. Here is a site were you can go learn your maths and time yourself on Prototec.
